Without it, showing the keyboard caused the keyboard to display, and 
then vanish again in a fraction of a second, and send an ENTER key Then 
it would pop up again, and vanish again with another ENTER, and it would 
repeat until close the program.

When I turned on CompatibilityHacksTextInputEmulatesHwKeyboard then the 
keyboard (at first glance) appeared to start working correctly.

Ah, that explains why it would not hide automatically.

Also, after more testing this morning, I can see that the first call to 
show_virtual_keyboard shows it okay, but if I leave it in screen and 
rename a hero again, then it toggles off.

So I am definitely not doing things right yet. I'll try again to get it 
working without the compatability hacks.

Oh, I had no idea that those existed. I found the 
SDL_ANDROID_CallJavaShowScreenKeyboard just by grepping the files in 
sdl-android/projects/jni/sdl-1.2 and I failed to notice the better 
functions. I'll try them next.

How do I check a sub pointer for nullity? I can see how to check 
functions that require >0 arguments, but how do I do

  IF subpointer = NULL THEN

Without executing the sub or argumentless function?
